NUT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 432,522, dated July 22, 1890.'

Application tiled March 19, 1890. Serial No. 344,514. (No model.)

To all whom it may concern:

Be it known that I, GEORGE J oNATHAN FOR- REY, a citizen of the United States, residing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented a new and useful Nut-Machine, of which the following is a specification.

This invention has relation to thatclass of metal-working machines employed for the stamping and otherwise forming of nuts and Washers; and among` the objects in view are to provide a machine for the above purpose Which Will automatically stamp and form the nut from a blank of metal, subsequently punch the same, and afterward deliver the uut therefrom, said machine to be provided with suitably-timed mechanism for accomplishing these successive steps.

Other objects and advantages of the inven tion will hereinafter appear in the following description and will be particularly7 pointed out in the claims.

Referring to the dra-Win gs, Figure l is a perspective of a nut-forming machine construct ed in accordance with my invention. Fig. 2 is a side elevation, the iiy-wheel at thatside of the machine being removed. Fig. 3 is a rear elevation. section. Fig. 5 is a transversehorizontal section through the vertically-sliding head. Fig. (5 is a vertical transverse section through said head and through the bed. Fig. 7 is a detail in perspective of the dic-carriage. Fig. 8 is a detail in perspective of the crown-forming die. Fig. J is a face view of the cam for operating the rock-shaft which operates the car. Fig. 10 is a perspectivein detail of the stamp` `guiding plate. Fig. 11 is a detail in perspective of the rear end of the rock-shaft, illustrating the adjustable sliding block. Fig. l2 is a detail of the forming-plate. Fig. 13 is a detail in perspective of the head-operating lever. Fig. la is a detail in perspective of the head, the Wheels being taken from the rear. Fig. 15 is a detail in perspective of the stamp detached.

Like numerals of reference indicate like parts in all the figures of the drawings.

Upon any suitable base, as 1, there is mounted a pair of vertical standards 2, which have their front ends at their upper portions and punching mechanism.

Fig. 4 is a central vertical slightly overhanging, as at 3, and provided with opposite inclined Ways et, forming a vertical bed for the reception of the stamping Passing transversely through the two standards is a shaft 5, suitably secured in position, and mounted pivotally upon the same, so as to freely oscillate, is a lever 6, which terminates at its front end in a toot-lied sector 7. In. rear of the shaft the lever is upwardly and rearwardly disposed and projects slightly beyond the rear edge of the standards. A sliding head 9, of oblong shape,is mounted in the vertical bed at the front end 0f the standards and has its opposite side edges provided with dovetailed groves l0 to fit the similarly-shaped ribs located at the sides of the bed. Secured to the rear face of the sliding head is a bracket 1l, from which there projects rearwardly a iange 12, the rear edge of which is toothed and is meshed by the teeth of the sector at the forward end of the lever (5. The flange ll is also provided with a curved slot 13, in which is mounted for slidingablock 14. Opposite straps 15 are rigidly securedto the toothed sector of the lever G, andtheir front ends are pivoted, as at 16, to the sliding block 14, so that in the vertical movement given the sliding head by the oscillating lever said block rides within its slot, as will be apparent, and a positive engagement of the teeth of the sector with the teeth of the head is insured.

Bearing-blocks 17 are secured opposite each other to the rear edges of the standards 2, and in the same there is journaled a crankshaft 1S, provided at its center between the standards with a cranked portion 19. The ends of the shaft beyond the standards each carry large fly-wheels 20, and at one side of the machine and outside of the adjacent standard carries a bevel-gear 2l,spaced from the adjacent fly-wheel bya collar 22. -Between the centrally-cranked portion and the bearing at the same side of the standards there is located a gear 23. vBelow the bearing-blocks 17 there is located a second pair of bearing-boxes 24, in which is mounted a crank-shaft 25, provided at one side of its center with an ordinary cone-pulley 2G and at the other side with a gear 27, which latter IOC) meshes with the gear 23 ot the crank-shaft.

A belt 2S leads from the cone-pulley to any suitable motor for operating the machinery.

Upon the crankshaft l0, at what may be termed the right-hand side of the machine, or that side opposite the beveled gear 2t, is mounted a disk t),\\'l1ich upon its outer surface is provided with a continuons cam-groove 30. Beyond the disk there ismounted on the shaft a gear 3l,whieh corresponds to the gear 2l at the opposite side ot the machine, and the gear 31 and the disk are spaced apart, as shown. A plate is securely bolted to the outer tace of the gear, and from the plate there projects outwardly a bearing-bolt E33, carrying a loose roller 3l. Outside ot the plate 32 and between it and the adjacent ily-wheel 2O is mounted the spacing-sleeve 22.

Upon the upper end of the standards there is mounted a bcaring-post 35, provided at its upper end with a bearing perforation, and through the same there passes a bearing-Inn 3G, upon which is mounted a balancing-lever 3S. The balancing-lever 38 is formed in opposite sections, which at their front ends are oppositely ilared or spread, and in the forward end of each ot said sections there is pivotally connected, as at 40, the upper end ot a vertical connecting-bar il, the lower ends of the bars being pivoted, as at 42, to the upper bifureated ends of a pair of brackets 43, secured to the upper edge and near the opposite sides ot` the vertieally-sliding head tl. The rear ends of the later-sections 3S clamp between them the inner end ot' a poise-beam 4l, upon which there iis mounted a counterbalaneing-weight 45. rlhc weight is movable upon the beam and atoppositc axial points is bored and provided with binding-screws 4U, the inner ends of which bind upon the beam and thus maintain the weight rigidly thereupon.

Upon the upper ends of the standards, and at a point vertically above their overhang-ing t'ront portions, there is provided a pair ot opposite journal-boxes 7, and in the same there is mounted thctrausverse crank-shaft 4S, the opposite terminals oi' which outside of the standards are each provided with large bevelgears 10. 'lhe central portion ot the crankshaft is cranked, as at 50, and journaled thereupon is a knuckle-jointed link 5l, provided at its lower end with a loosely-pivoted swivel 52, the lower end ol which is centrally bored and threaded, as at The lower edge of the slidinghcad Sl is provided with a recess 55, the opposite walls ot' which are undercut or dovetailed, as at 5t?.

57 represents the stamp or t'ormer, and the same is similar in cross-section to the plan ot the nut or washer to be formed. ln this instance I have shown a stamper adapted to form a hexagonal nut, and the same, therefore, is hexagonal in eross-seetirm, The upper portion ot the stamp or former is removably connected to the head t) and is cent-rally bored, as at 5S. The head t) isalso vertically perforated, as at 5f), which perforation or opening agrees in location and size with that oi the stamp. Mounted in the two openin gs-namel y, that of thchead andthestampw and adapted for vertical reciprocation therein, is the punch GO. The punch 00 is of a length greater than the combined length of the head and stamp and has its upper end provided with a jam nu t. Gl, threaded on the same and entered in the lower threaded end of the swivel so that said punch may be removed, and is also capable of a slight vertical adjustment. Brackets G2 are secured. diagonally opposite each other at the outside of each of the standards 2, the outer ends of: said brackets being provided with journal-boxes G3. ln each pair of journal-Mixes (i3, at cach side of the machine, there is mounted an inclined shat't til, which shatts are each provided at their extremities with beveled pinions G5. The upper pair ot pinions (i5 mesh with and drive the bevel-gears it), and the lower pair of pinions mesh with and are driven bythe gears 2l and 31, mounted upon the power-shaft l).

As before stated, the rear end ol the lever t3 is upwardly and rearwardly disposed, and pivoted to the extremity of the saine, as at (5c, is the upper biurcated end of a lilik o7, the lower end of which is provided with a box US, which receives the crank portion of the shaft lf), and through the medium ot' the link the lever (i is oseillated vertically. 'lhe lower front ends of the standards are continued beyond the ovcrhanging portions, and mounted upon the same are opposite front and rearconl'iecting sides ttheombiningto form the bed ot' the machine. rlhc right-hand side ot the bed, or rather that portion of the stand ard 2 forming the same, is recessed, as at 7l, in its upper halt', and formed upon the inner surfaces ot the front and rear sidcsot thc bed are ways 7 2, which ways are on a level with the bottom of the recess and are continued at the right-hand side of the bed by means ot an invertedL-shaped table 73, provided with opposite vertical llanges 74. rl`he omwosite or lett-hand side of the bed has itslowcr h'alt' provided with a' discharge-opening 75, and leading to the openingl and. from about the center ot' the opposite ways within the bed is an inclined discharge 7H.

Mounted for slidinglaterally upon the ways ot the bed and upon the inverted-L-shaped extension thereof, or what was heretofore designated as the table, is the dic-carriage 77, the under portion ot' which is provided with two opposite longitudinally-disposed contactsurfaces 7S, movable upon the opposite ways ot` the bed, and the upper surface ot' whiehis provided with a rectangular recess 7l). Seated within the recess 7S) and secured in its position by screws 90, inserted through the walls oi' the recess, is a die-plate S1, which, by reason ot' the screws, is removably secured in positioinso thatvarious forms ot dies may be substituted t'or the same. The plate Sl,

and also the carriage, is provided with a vertical opening1 32, and surrounding said opening inthe upper surface of the plate is a countersunk and in this instance hexagonal recess 33.

Superimposed over the bed is a bed or forniing plate S4, which at its rear edge is secured to the front edges of the standards by L- shaped an gle-plates 89, securely bolted to both the st-andards and plate, and at its front by double-L-shaped plates 90, securely bolted at. their upper ends to the plate and at their lower ends to t-he front of the bed. The bedplate or former is also provided near its 'center with an opening 91, in this instance of hexagonal shape, and exactly agreeingin size with the stamp 57, in the path of which'the opening is arranged, and said opening is also coincident with the hexagonal countersunk recess in the die-plate directly under the same.

At the right-hand side of the machine there is located a pair of laterally-extending horizontal brackets 92,provided at their upper ends with journal-boxes 93. The inner ends of the brackets are irregular, conforming to the edges of the base and feet of the machine, and are securely bolted to. the standards 2 and to the feet of the standards, as at 01. J ournaled in the brackets is a rock-shjaft 95, which extends from a point in rear of the standard to a point opposite the center of the bed, at which end it is provided with a rockarin 9G. The opposite end of the shaftis provided with a fixed yoke 97, and connecting the terminals of the yoke is a threaded rod 98, jammed in position by means of opposite j ain-nuts 99. The ends of the rod are squared, as at 100, to receive a wrench.

101 represents a block or slide having a threaded perforation 102, through which the threaded rod passes, andby rotating said rod by means of an ordinary wrench applied toits squared end it will be apparent that the sliding,` block may be operated back and forth upon said rod and within the yoke, so that said sliding block may be adjusted to or from the axial center of the rock-shaft. Projecting from the sliding block 101 is an arm 103, in the eX- tremity of which there is pivoted, as at 104, a vertically-disposed connecting-rod 105, the upper end of which is pivotally connected, as at 106, to a two-way connecting-shackle 107, the upper end being pivoted, as at 10S, to a horizontal counterbalancing-lever 109, which lever is pivoted, as at 110, at its inner end to an L-shaped bracket 111, bolted to the outer surface of the right-hand standard 2. This lever lies between the gear 31 and the cam-disk, and is provided with a -laterallyprojecting pin 112,carrying an anti-friction roller 113, which enters and travels within the continuous cam-groove ofthe disk. Y

The outei'end of the die-carrying car or carriage is provided with a pair of bifurcated lugs 114, and in the same `there is pivoted, as at 115, a loose shackle 11G, the opposite end thereof being pivoted, as at 117, to the eX- tremity of the rock-arm 96.

A pair of bracketsl 119- are secured to the standard 2 at the right of the machine and near the base,- which brackets are provided with perforated bearing-lugs 11S, in which is mounted a horizontal reciprocating lockingbar 119, provided at its end with a disk 120, from which there projects a locking-bolt 121. From the back of the disk there projects rearwardly a guide-pin 122, the rear end of which is mounted for movement in guideperfora tions 123, formed in the lugs 110, so that while the locking-bar 119 is free to reciprocate it is maintained by the locking-pin against any rotary movement. A coiled spring 121 encircles the locking-bar between the disk at the end of the'same and the front pair of brackets, thus normally forcing the locking-bar for `ward or to a locked position, and when the die-supporting car is within its bed the bolt ot'V said locking-bar is maintained within a bolt-receiving opening 125 formed in the side of said car.

Vertically-oppositebrackets 126 are secured to the right-hand standard 2, which brackets are provided with bearing-openin gs to receive a vertically-reciprocatingrack-bar 127,which is therefore arranged at a rightangle to the locking-bar 119. The rack-bar is provided near its upper end with a shoulder 123 and above said shoulder is cylindrical, and interposed between'the shoulder and the upper bracket is a coiled spring 129, which normally depresses the rack-bar so that'its lower locking end rests upon the locking-bar 119, and when said locking -bar is withdrawn to the rear against the tension. of its coiled spring said locking end engages a notch 130, formed in the locking-bar, thus retaining the locking-bar in an unlocked position or out of engagement with the reciprocating die-carrying car. Above the rear end of the locking-bar there is secured to the standard 2 of the machineY a laterally-projecting short bearingstandard 131, and upon the same there is pivoted an oscillating lever 132, the lower end of said lever being pivotally connected, as at 133, to the rear .end of the locking-bar 119. The upper or free end of the lever lies in the path of the friction-roller 3 1, projecting from the disk -or plate 32, bolted to the beveled gear 31, and at each revolution of the iiywheels 20 and their shaft said roller is broughtinto contact with the upper end of the lever, throwing the same to the front and thus withdrawing the locking-bar against the tension of its spring, in which position it is locked by the rack-bar before described.

A bracket 131 is secured to the right standard 2, near its upper front portion, and in the same there is pivoted a bell-crank lever 135, the rear extremity of which is pivotally connected, as at 13G, to a connectiiig-rody '137, which-depends at the side of the standard and is connected to the rear end of a horizontal IOO IIO

lever 13S, mounted upon a bearing 139, projeetin'g from the standard. The lever 13S is provided above its bearings with a verticallydisposed arm or branch 1li), and secured to said arm by a bolt lll is a disk 1&2, which disk is journaled upon a bearing of the lever 13S and basa portion of its periphery toothed, as at M3, said teeth meshing with the teeth of the rack-bar 127 and serving to elevate said rack-bar, so that its locking end will be disengaged from the notch in the locking-bar at each oscillation of the disk and its lever. The crankshaft 1S at the right of the machine and between the bevel-gear i9 and the bearing for the shaft is provided with a disk lll, and adjacent to the periphery of said disk occurs the upper end of the bell-crank lever 135. The periphery of the disk is provided with a cam-lug 1&5, adapted to come into contact with the front upper end of the lever at each revolution of the disk and thus oscillate the same upon its pivot, which movement, it will be observed, causes a depression oi' the opposite end of the bell-crank and the horizontal lever 13S and a partial rotation or oscillation of the toothed disk, which acts to elevate the rack-bar.

This being the construction of the machine, the operation of the same is as follows: A bar of metal is introduced either by hand or any automatic feed over the opening in the forming-plate Sl, and the machine being in oper ation the following movements of the parts will take place: Through the medium of the counter-shaft, which is driven by anysuitable motor connected by belting, the power-shaft 19 and its ily-wheels 2O are driven in the direction indicated by the arrows. A revolution of the power-shaft by reason of its cranked portion elevates the rear end of the main lever G, and the sector formed at the front end of said lever, meshing with the teeth of 'the bracket 11, secured to the rear face of the sliding head 9, causes said head to descend in a positive manner, carrying with it the stamp 57, which, being arranged directly over the openi ng in the formingplate Si, forces a blank ol' metal into the opening of said plate and down upon the eountcrsunk recess of the dieplate, which recess serves to mold or forni the curved upper face or what is commonly known as the crown of the nut. Thelower face or end ot the stamp 57 being perfectly true and the power with which it is forced down being very great, any jagged edges or upset portions of the metal blank will be stamped into the blank and destroyed, so that up to the present stage et' the operation of the machine we have a perfectly-formed nutblank, the angles of which are perfectly true and ofan exceedingly finished exterior. A further revolution of the power-sbaft by its beveled gears 21 and 3l, it will be observed, iurther turns or rotates the opposite inclined shafts and the beveled gears i9, which latter rotate the crank-shaft -lS and bring the crank thereof to such a position as to lower the `head is elevated, and with it the punch, the

counterbalancing-weight 4G serving to aid in the elevation of the head, thereby lightening the strain upon the machinery. At the time that the stamping of the blank and punching of the same take place, or rather previous thereto and during the same, it will be observed that the locking-pin ot the locking-rod 1.38 is within the opening formed in the dieearrying ear, so that the latter is absolutely prevented from any movement whatever during the operation of punching and forming, so that also the punching is perfectly true with the axial centerof the nut-blank. After the stamping and punching have taken place and the punch and sta-mp have been elevated above the nut the canrdisk 2.() assumes such a position as to elevate the rock-shaftfoperat ing lever 38, which lever is provided with a counterbalancing-wcight 146. rlhe elevating of the rear end of this lever, it will be observed, through the medium of the vertical connecting-rod, causes an oscillation et the rock-shaft 95, which, through the medium of its rock-arm, withdraws the die-carrying car. This withdrawal of the die-carrying ear laterally from the bed of the machine leaves the nut-blank thus formed in the opening ot' the plate 84, so that said blank falls from said opening upon the inclined discharge within the bed. A further movement of the machine brings the cani-disk to such a position as to permit the weight liti to depress the lever and oscillate the rock-shaft 95 in a reverse direction ready for a subsequent repetition of the operation betere described. After the punching and stamping operation and previous to the withdrawal of the die-carrying car for the purpose of delivering the nut-blank the roller 3l on the disk 32 comes in contact with the upper end and rear face ot the oscillating lever 132, which serves to throw said lever to the front and its lower end to the rear, thus causing a withdrawal ol' the locking-bar from the die-carrying car and permitting the operation et withdrawing the car to take place. At the time that the bar is withdrawn it will be observed that the rack-bar is ready to en gage the notch of the lockingbar, so that the latter is maintained in its retracted position during the movement of the rock-shaft and the discharge of the nut-blank. When, however, the rock-shaft is at rest after a return ol' the die-carrying car, the cam-lug 1l5 is in position to strike the upper end of the bell-cran k lever 135, thus causing a tilting of the lever, a depression of its re'ar lower end, and an os- ISO IIO

cillation of the partially-toothed disk lil and its horizontal operating -lever 138. Such movement, as before described, raises the toothed rack-bar, so that its lower end is disengaged from `the notch of the locking-lun',

and the latter' is shot forward, so that its bolt turned, as at lfl', and removably bolted, as atV 14S, to the sides of the head, and the transverse portion of the plate is recessed or provided with an opening 149, which agrees in contour with the stamp and serves as a guide for the same duringitsreciprocations. In removing the stamp the guide-plate is detached.
